2015 GMC Sierra Denali Features Magnetic Ride Control


Just the Facts:
  • All 2015 GMC Sierra Denali half-ton models feature standard magnetic ride control.
  • According to GM, this marks the first time this advanced suspension system has been offered on a full-size pickup truck.
  • Magnetic ride control uses special fluid and electromagnetic coils to adjust damping for a more refined ride while maintaining payload and towing capacities.

DETROIT — All 2015 GMC Sierra Denali half-ton models feature standard magnetic ride control, which GM says marks the first time this advanced suspension system has been offered on a full-size pickup truck.

According to GM, magnetic ride control provides a more refined ride while maintaining the truck's payload and towing capacities.

The 2015 GMC Sierra Denali is expected to arrive at dealerships later this year. Pricing has not been announced.

The 2015 Sierra Denali half-ton's maximum payload is 9,400 pounds for a four-wheel-drive model with the standard 5.3-liter V8 engine and 5-foot 8-inch cargo box, and its maximum trailering capacity is 9,400 pounds for a two-wheel-drive version with either the 5.3-liter or available 6.2-liter V8, also with the 5-foot 8-inch box.

"With magnetic ride control, the 2015 Sierra Denali delivers a smoother, more confident driving experience without sacrificing the capabilities customers expect from a GMC truck," said Jeff Luke, executive chief engineer, in a statement. "The responsiveness of the system makes this full-size truck feel and drive like a luxury vehicle — and one that's more comfortable on long trips, especially when trailering."

Magnetic ride control works with conventional-looking tube shock absorbers, but in this case they're filled with a special magnetorheological fluid that contains minute iron particles. When subjected to a magnetic field, generated by electromagnetic coils, this fluid is able to increase its viscosity, or thickness, almost to the point of becoming a solid.

The 2015 GMC Sierra Denali features GM's third-generation magnetic ride control system, in which sensors monitor road and vehicle conditions every millisecond and send signals to the shock absorbers' coils, which in turn vary the strength of the magnetic field to increase or decrease the amount of damping as needed.

Although various types of adaptive suspension preceded it, GM's magnetic ride control first appeared on the 2002 Cadillac Seville STS. Since then, versions of the system have appeared on many other GM vehicles, including the 2015 Corvette Z06, the 2015 Cadillac Escalade and the 2015 Chevrolet Camaro ZL1.

Other brands to feature the technology have included Acura, Audi, Ferrari and Range Rover.

Edmunds says: We can see the attraction.
